ELISA assay was performed to measure the secretion of IL-6 and IL-10. MTT assay was used to determine the cell viability and proliferation. Western blot was used to assess the phosphorylation of NF-kB, Erk1/2, JNK, P38, JAK2, and STAT3. Results: Salidroside impaired the proliferation of intestinal epithelial cells at high concentrations (P< 0.05) and down-regulated interleukin-6 (IL-6) production induced by LPS (P<0.05). Western blot results showed that salidroside repressed the phosphorylation of NF-kB, Erk1/2, JNK, P38, JAK2 and STAT3 (P<0.05) and attenuated the activation of NF-κB, MAPK, and STAT3 pathways. Moreover, the expressions of α-defensin 5 and 6 were rescued by salidroside after LPS or SAC triggering (P<0.05). Conclusion: In summary, salidroside suppressed the expression of IL-6 and elevated the expression of defensins in LPS-activated intestinal epithelial cells through NF-κB/MAPK and STAT3 pathways. The mechanism revealed here may be potentially useful for the treatment of IBD with salidroside. %U https://ijbms.mums.ac.ir/article_11839_b291d0dd76171e7ed07c9a3c9dbf1bc7.pdf
